For enhanced safety, the front and second-row seat shoulder belts of the Mercedes EQB have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The GMC Hummer EV SUV doesn’t offer pretensioners for its rear seat belts.
The EQB’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Hummer EV SUV doesn’t offer pre-crash pretensioners.
The Mercedes EQB has a standard driver’s side knee airbag mounted low on the dashboard. The knee airbag helps prevent the driver from sliding under the seatbelts or the main frontal airbag; this keeps the driver better positioned during a collision for maximum protection. A knee airbag also helps keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Hummer EV SUV doesn’t offer knee airbags.
The EQB has standard head airbag curtains for front and middle row seats which act as a forgiving barrier between the driver and outboard passenger's upper bodies and the window and pillars. Combined with high-strength steel door beams and lower side airbags this system increases head protection in broadside collisions. The Hummer EV SUV doesn't offer side airbag protection for the head and are only available for the front seats.
Both the EQB and Hummer EV SUV have rear cross-traffic warning, but the EQB has Active Brake Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The Hummer EV SUV’s Rear Cross Traffic Alert doesn’t automatically brake.
Both the EQB and the Hummer EV SUV have standard driver and passenger frontal airbags, front side-impact airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors, available lane departure warning systems and around view monitors.
